    Retrofit Renewable Energy FAQs

    Can an older home have a heat pump installed?

    Yes. With correct design and potential upgrades to insulation or radiators, most existing properties are suitable for heat pump systems.

    Do solar panels work on older roofs?

    In many cases, yes. We assess roof condition and structure during the initial survey.

    Will I need to upgrade my radiators?

    Possibly. Heat pumps operate at lower flow temperatures, and some emitters may require resizing.

    How disruptive is a retrofit installation?

    Our team plans installations carefully to minimise disruption and complete work efficiently.
